The Radiomir PAM01572, seen from the bench

The Panerai Radiomir PAM01572 is a 40mm stainless steel watch that directly continues the 1936 prototype commissioned by the Italian Navy for secret underwater operations. The cushion case features welded strap lugs, bare onion crown, and displays military aesthetic with a dirty white dial and Paneristyle numerals in Super-LumiNova. The manual-wound Panerai P.900 calibre offers 72-hour power reserve with hours, minutes, small seconds at 9 o'clock, and date window at 3 o'clock. Case crafted in 316L surgical steel with matte satinized finishing, 100-meter water resistance, and anti-reflective sapphire crystal. Strap size: 22mm.

Frequently asked questions

What is the lug width of the Panerai Radiomir PAM01572?

The lug width of the Panerai Radiomir PAM01572 is 22mm, a construction specification that corresponds to the compact 40mm case diameter. This width can be verified by positioning a digital caliper between the internal metal terminals, and represents the functional space where the strap is secured via articulation pins without forcing.

Which strap is most suitable for the Panerai Radiomir PAM01572?

For the PAM01572 in satin steel, we recommend cognac or dark brown alligator for military aesthetic coherence, or vegetable tanned calf in sand tones that ensures superior durability. Dark grey or navy NATO represents a versatile alternative for formal settings, while black rubber is recommended for frequent diving.

How do I change the strap on the Panerai Radiomir PAM01572?

To change the strap, position the watch with the dial facing downward. Using a spring bar tool, gently compress the articulation pin from the opposite side until it protrudes partially, then extract the pin completely. Insert the new strap by aligning the terminals to the lug ends, and reintroduce the pin ensuring it is fully locked on both sides.

Can I use an aftermarket strap compatible with the Panerai Radiomir PAM01572?

Yes, all straps with 22mm lugs are compatible with the PAM01572, regardless of brand. Milano Straps offers customizable handcrafted straps in leather, alligator, and NATO, specifically designed for luxury watches with this measurement. Casati Milano's 18-month warranty covers any manufacturing defects.

How long does a leather strap last on a Panerai like the PAM01572?

Durability depends on material and usage. An alligator strap, with dense and regular fibers, lasts 4-6 years with daily wear. Vegetable tanned calf has similar durability but requires periodic maintenance with specific creams. In humid environments or with frequent diving, switching to NATO or rubber preserves the original leather. Milano Straps guarantees 18 months on all handcrafted straps produced.
